Polymaker ASA Filament 1.75mm Black - Weather Resistant Outdoor PLA

In this review the Polymaker PolyLite ASA 1.75mm filament is evaluated as a practical choice for makers who need durable outdoor parts; its single biggest advantage is consistent, weather-resistant prints that tolerate UV and higher operating temperatures. The reviewer tested it for functional prints and small RC components, noting that the filament behaves much like ABS but with improved resistance to environmental stress cracking and sunlight. Those looking for an ASA that prints with familiar ABS settings and offers improved longevity outdoors will find its balance of toughness and heat resistance compelling.

Key Features

• Weather resistance: The filament combines ABS-like strength with UV resistance so printed parts last longer outdoors without rapid degradation.
• High heat tolerance: Rated to withstand up to 100 C (212F), it is suitable for functional parts exposed to elevated temperatures.
• Mechanical strength: High toughness and impact resistance make it a good option for functional and load-bearing parts such as mounts and accessories.
• Eco-minded packaging: The upgraded packaging uses a fully recycled cardboard spool and box to reduce plastic waste from shipping and storage.
• Printer compatibility: Uses standard ABS-style settings (nozzle ~250 C, bed ~90 C, speed ~50mm/s), so users familiar with ABS will have a minimal learning curve.
• Support: Lifetime technical support is offered for print troubleshooting and setup questions to help achieve reliable results.

Who It's For

This filament is aimed at hobbyists and small-scale fabricators who need durable outdoor parts like RC plane components, car accessories, garden fixtures, and other functional items that face sunlight and weather. Users who already print with ABS will find the transition straightforward because the material prints with similar temperatures and handling.

It is less suited for beginners who cannot control bed adhesion or who lack access to an enclosed printer for large items, since ASA can warp on big flat pieces and some users report mixed bed adhesion results. Those who need perfectly color-accurate or glossy aesthetic-only prints may also prefer alternative materials.

Pros & Cons

Pros

• Prints with consistent quality using standard ABS settings for reliable functional parts.
• Resistant to UV and environmental stress, extending the life of outdoor prints.
• High heat resistance and impact toughness suitable for demanding applications.
• Environmentally friendlier packaging with a recycled cardboard spool.

Cons

• Some users report mixed bed adhesion and occasional warping; large parts benefit from an enclosed build chamber.
• Color consistency received mixed feedback from customers, so expect slight variations versus label expectations.

Frequently Asked Questions

Is this filament suitable for outdoor use?
Yes. It is formulated to resist UV and environmental stress cracking, making it suitable for outdoor functional parts.

What printing settings should I use?
Start with a nozzle temperature around 250 C, bed temperature near 90 C, and print speed about 50 mm/s; adjust as needed for your machine.

Do I need an enclosure for large parts?
For large flat components, an enclosed printer is recommended to reduce warping and improve bed adhesion.
